BINDER ATTACHIIENT.

To all whom it may concern: v

Be it known that I, JOHN E. 'RDBB, a citizen of the United States, residing at Hallowell, the county of Cherokee and State of Kansas, have invented certain new and use-.

ful Improvements in Binder Attachments, of

which the following is a specification, reference being bad to the accompanying drawy inventlon relates to nnprovements in self binding harvesters and more particularly to means for positively feeding the grain down the, grain table .to the pee rs or bundling mechanism.

eral use the grainis delivered from the cutting apparatus by an elevator upon the top of a downwardl inclined grain tableat the lower end of W 'ch is arranged mechanism for packing the grain into bundles and tying the bundles. When the grain being harvested is damp and when it has fallen down and is short and thin, it will not readily feed down the grain table to the packers after it has been deposited upon the topof the table Such grain tends to adf by the elevator.

' here to the table and to choke the packing and bundling mechanism.

The object of the resent invention is to provide a simple an inexpensive mechanism which will effectively overcome the above noted objection to harvesters and which will be in the form of an attachment so that it can be readily applied to harvesters now in use.

With the above and other objects in view the invention consists of the novel features of construction and the combination and ar rangement of parts hereinafter described and claimed, and illustrated in the accompanying drawings in which Flgure 1 1s a View of a portion of a well known form of binder showlng the application of my invention thereto; Fig.2 is a per- 45. spective view of the attachment removed from the, machine; Fig. 3 is a detail section taken on the plane indicated by the line 3-3 in Fig. 2; and Fig. 4 is a perspective of the pivot bracket or support. I

While in inventlon may be adapted for use upon a inding machine of'an form and construction, the present embodiment of it is in the form ofan attachment especially Specification of Letters Patent. Application filed September 11, 1907: Serial No. 892,379.

In the self binding harvester now in gen- Patented May 12,1908.-

designed for use u on the binder known on the market as the eering Ideal Binder. This binder as shown in Fig. 1 has a downwardly inclined grain table T at the lower end of which is a bundling mechanism P adapted to receive the grain and form it into bundles, and at one slde of which is a butt ad'usting mechanism 0 operated by a crank s aft S.

' The 1 grain table T is supported from the frame of the machine at the upper end of the a usual endless elevator and provided with a cover t.

My invention is designed to force or posi tively feed the grain deposited upon the top of the table T down the same to the bundling mechanism P and it comprises a raking or packing member 1 arranged ongitudinally of'the'table beneath its cover t'and adapted to be reciprocated as presently explained. This member 1 is preferably in the form of a bar or stafi havingupon its lower side a plurality of downwardly inclined s ring teeth 2 which engage the grain u on t 'e table and force it downwardl as t e rake or packer staff is reciprocate The teeth 2 are preferably arranged in a longitudinal row and are constructed of resilient metal, each having at its inner end a straight portion 3 and a right angularly bent 'spur 4'which is driven into the staff 1 as shown in Fig. 3. Staples 5 e'iigage' with the portions 3 of said teeth and are driven into the staff for the purpose of holding the teeth in longitudinal aliner'nent with the staff. The'stafi or bar 1 is of such length that when reciprocated its teeth 2 feed the grain on the table to the bundling mechanism P. The rake or acker staff is preferably operated by a roc ing beam or ever 6 to one end of which it is ivotally connected by a bolt or the like-7 his pivotal connection is strengthened b providing upon the upper end of "the sta 1 a metal strap 8 havmg an offset end 9 between which and the staff 1 is arranged the rocking beam 6. The beam or lever 6 is pivoted intermediate its ends uponthe ivot stud 10 formed upon a sup or-tmg brac et' 11. The latter is substantial y V-shaped and'consists of two or other suitablefastenings. The beam or lever 6 may be operated from any moving art of the binder but upon the Ideal Deering inder I preferably operate it from the crank shaft S to which it is connected by a pitman 14. This pitman rod has at one of its ends an aperture 15 to receive the end of the crank shaft and at its otherend is formed aright angularly projecting pivot stud 16 to enter an a erture in one end of theibeam or lever 6. t will be seen that in order to connect the device to the binder it is only necessary to attach the bracket 11 to its frame and to remove the usual dotter pin in the end of the crankshaft S then apply the pitman rod 14 to said end and then replace the cotter pin! To enable the device to be readily removed from the-binder I preferably provide a cotter pin 17 in the pivot stud 10, so that when said cotter pin is removed the beam or lever 6 may be removed from the bracket 11. A cotter pin 18 is also preferably provided upon the pivot 16 so that the pitman rod and lever may be disconnected if desired.

Any suitable means may be provided for guiding the rake or acker stafl 1 and allowing it to have a imited lateral swinging movement but I preferably employ a rod or link 19 which is arranged substantially parallel with the beam or lever 6 and has one of its ends pivotally connected at 20 to the cross bar 13 of the bracket 11 and its other end pivotally connected at 21 to the staff 1 at a suitable distance from the pivot bolt 7 This construction it will be observed will cause the staff 1 to be maintained at all times with its length longitudinally of the table T so as to force-the grain squarely down the same.

In operation, the motion of the crank.

shaft S is imparted by the itman 14 to the rocking beam or lever ,6 w ich latter oscillates and reciprocates the rake or packerstaff 1 longitudinally above the grain table so that the teeth 2 of said stafi engage the grain and force it downwardly to the oscillating arms of the bundling mechanism P of the machine. Owing to the resiliency of the teeth 2' and to the downward inclination of their ends they'will slide over the grain as the stafi 1 is raised and then engage the grain and force it downwardly as the staff is lowered or moved downwardly over the table.

understood that various changes in the form,

proportion and minor details may be resorted to withoutde arting from the spirit or sacrificing 'any of 't e advantages of the invention and that I therefore do not limit myself to grain table and a crank shaft, of a bracket, a

the precise construction shown and described. I

Having thus described my invention what I claim is:

1. In a binder, the combination with an inclined grain table, of a rake bar or packerstaif arranged longitudinally above the table, a longitudinal series of spurs carried by said bar or staff and rojecting from the bottom of the latter, sai spurs bein inclined down- 7 wardly and stubbleward an adapted to engage. the grain u on said table and feed it. positively down t e same, and means for reciprocating said bar or packer stafi longi tudinally I a 30 2. In a hinder, the combination'with an inclined grain table, of a rake bar or packer staff arranged longitudinally above the table,

a longitudinal series of spurs carried by said bar or staff and rojecting from the bottom of the latter, said s urs being inclined downwardly and stubb eward and adapted to engage the grain u on said table and feed it positively down t e same, and a lever connected to the upper'end of said bar or staff for reciprocating it longitudinally abovethe parallel .with the lever and pivotally con- 00 nected to the staff and an operating means connected to the other end-of the lever for oscillating the same.'
